There has been a spate of attacks on Catholic churches in France since the start of the year. On Sunday last L’église Saint-Sulpice in the centre of Paris was badly damaged in an arson attack. Last Friday Ines Madani, 22, was sentenced following a three-day trial during which she was accused of encouraging would-be jihadists to go to Syria and participate in attacks against France and jailed for 8 years. She is also due to be tried later this year for her part in a failed car bomb attack on Notre Dame three years ago. The fire has happened in Holy Week and with the total destruction of the roof one wonders if the true cause will ever be established. I'm not normally a conspiracy theorist but not a huge believer in coincidence either.

Getting the ship out of the broken fock with coffer dams in place will be a nightmare and won't happen quickly. The news blackout likely emphasises the seriousness of the situation.
